Question

I was wondering how to go about doing something such as this:

I need to create a Form with a specific number of buttons based on an integer value representing the number of buttons needed, then give them their own specific names so that each can have their own unique event handlers.

A real example I can think of doing this would be the Windows log-in screen, where the number of controls created is based on the number of users and whether there is a Guest account or not. How do you think that they programmed that?

Thank you.

Answer 1

for (int i = 0; i < 5; i++)
{
  Button newButton = new Button();
  newButton.Name = "button" + i.ToString();
  newButton.Text = "Button #" + i.ToString();
  newButton.Location = new Point(32, i * 32);
  newButton.Click += new EventHandler(button1_Click);
  this.Controls.Add(newButton);
}

private void button1_Click(object sender, EventArgs e)
{
  if (((Button)sender).Name == "button0")
    MessageBox.Show("Button 0");
  else if (((Button)sender).Name == "button1")
    MessageBox.Show("Button 1");
}
